(Cell-free assay)

13 nM

In vitro
In vitro	The combination therapy of Seclidemstat (SP-2577) with checkpoint inhibitors may induce or augment immunogenic responses of SWI/SNF-mutated ovarian cancers. Seclidemstat promotes endogenous retroviruses (ERVs) expression and activation of IFNβ pathway in small cell carcinoma of the ovary hypercalcemic type (SCCOHT) cell lines. Seclidemstat (3 μM) promotes PD-L1 expression in SCCOHT COV 434 pIND 20 BRG1-2.7 cell line.^[1]
Cell Research	Cell lines	Small cell carcinoma of the ovary hypercalcemic type (SCCOHT) cell lines, ovarian clear cell carcinomas (OCCC) cell lines
	Concentrations	1μM,3 μM
	Incubation Time	72 h
	Method	The SCCOHT and OCCC cell lines are seeded in T-25 tissue culture treated flasks at 3 x 10₅ cells in 5mL of the appropriate phenol red free complete growth medium. After 48 h, at 70–80% confluency, the cells are treated with 3μM or 1μM of Seclidemstat. After 72 h, the media is collected from the flasks and stored at -80°C until use for various assays.

In Vivo
In vivo	SP-2577 (Seclidemstat) is an inhibitor of lysine-specific demthylase KDM1A (LSD1) potential antineoplastic activity against pediatric sarcomas.
Animal Research	Animal Models	C.B.17SC scid−/− female mice
	Dosages	100 mg/kg
	Administration	i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
